Global warming is a complex problem that often sparks policy debates. When writing nigh it, stick to the facts and make sure that your thesis statement -- the fundamental exclamation of your essay -- is supported past research. Some global warming topics have produced extensive research worldwide and can serve as topical guides in formulating your thesis statement.

Manmade Causes versus Natural Causes

The causes of global warming are complex, including natural and man-fabricated emissions of carbon dioxide and methane. Use your thesis to highlight the difference between natural sources and human being-fabricated sources. For instance, according to the Environmental Protection Bureau, carbon dioxide concentrations in the atmosphere take risen from 280 parts per million in the 18th century to 390 parts per 1000000 in 2010. Human activities release more than thirty billion tons of carbon dioxide each year, or 135 times every bit much as volcanoes. Focus your thesis on this discrepancy, how man-fabricated carbon dioxide sources such as fossil fuel consumption, have eclipsed natural sources of the gas.

Rising Temperatures and Declining Sea Ice

Your thesis argument may focus on the human relationship between ascent surface temperatures and failing bounding main ice, specifically ice in the Arctic. For example, since 1901, sea surface temperatures have risen at an average rate of 0.thirteen degrees Fahrenheit per decade, with the highest rates of change occurring in the past three decades alone, according to the EPA.

Your thesis may constitute the inverse relationship between these rising surface temperatures and the shrinking ice coverage in the Chill. Arctic sea ice extent in Dec 2014, for instance, was the ninth lowest in the satellite record. The rate of pass up for Dec water ice alone is 3.4 percent per decade, co-ordinate to the National Snow and Ice Data Middle.

Effects of Melting Glaciers on Water Supply

Forth with sea ice, many of the globe's glaciers are melting due to climatic change. Since the 1960s, the U.S. Geological Survey has tracked the mass of two glaciers in Alaska and one in Washington state, all three of which have shrunk considerably in the past 40 years.

Inquiry other mountain ranges and compare the glaciological data. Apply your thesis to respond the question of what melting glaciers will hateful for populations dependent on the water ice flows for their fresh water supply. For instance, much of Peru's population depends on Andean glaciers not only for drinking h2o merely for hydroelectricity.

Effects of Drought on Food Production

While global warming is projected to raise sea levels and flooding in coastal regions, it'southward also been credited for changes in weather patterns and extreme drought, according to the EPA. In the arid American Southwest, for instance, average annual temperatures have increased about 1.5 degrees Fahrenheit over the past century, leading to decreased snowpack, extreme drought, wildfires and trigger-happy contest for remaining water supplies.

Every bit drought still rages in this region, your thesis can explore the relationship between global warming and agriculture, specifically in California'south Central Valley, which provides produce for much of the country. Information technology'due south possible that hotter, longer growing seasons are beneficial to California crops, simply that shrinking water supplies threaten the viability of commercial agriculture.

Ocean Acidification and Global Seafood Stocks

Increased carbon dioxide emissions don't just impact our air quality. These emissions besides result in increased acerbity of our planet's oceans. An immense range of shellfish and other molluscs, such equally clams, oysters, venereal, lobsters and more, face up firsthand population refuse due to ocean acidification weakening their calcium carbonate shells.

Your thesis can explore the mechanics of body of water acidification as well as the potential economic bear upon to the fisheries that rely upon these marine animals for survival. You tin likewise explore the potential ecosystem impact for the predators that feed upon these animals.
